Lunar Halo has a clear base filled with color shifting and silver holo glitters from tiny tiny shimmer-like to huge hexes. It's really sheer, the pictures show three coats and you can still clearly see my nail below it. If you want an opaque finish with this one, you have to layer it over a opqaue base. It's really glittery, but one generous coat of KBShimmer Clearly On Top was enough for a smooth finish.
Femme Fatale polishes are available at their shop , Norway Nails and Color4Nails.
